Tape guide 39a has a truncated cone shaped washer 128 fixedly mounted onthe end thereof while upright plate 129 has a slot 130 through whichextends bolt 131 from guide 39a with a nut for holding said guide 39a invarious positions along said slot. A stop bolt 132 is in threadedengagement with plate 129 and limits the movement of said guide which inturn is pivotally connected to plate 129 by a nut and bolt 133 extendingtherethrough. A pair of rollers 134 ride on the under-side of H-beam 32and are rotatably carried by axles 135 extending from carriage 35 forretaining said carriage on said H-beam.

A plate 136 extends downwardly from and is iixedly connected to carriage35 and an eye bolt 137 extends through said plate and has a nut 138thereon. Spring 139 connects said eye bolt and the eye 140 of a lever141 pivotally connected by bolt 143 to said carriage. A cog 142 having a15 slanting end is adjustably carried by lever 141 and positioned forits edge to engage wire 4 on pulley 34 to prevent said wire from beingpulled from said carriage by slide 27.

A plate 144 is xedly mounted on and extends crosswise of said carriageand has a slot 145 therein.

A groovedroller 148 is rotatably mounted on said plate below said slot while asecond grooved roller 150 is rotatably mounted on said plate above saidslot. A third grooved roller 149 is rotatably mounted on slide 146 andWire 4 passes upwardly from pulley 34 to roller 148 and sinuously windstherefrom over rollers 149 and 150 to be given a bend or cast to conformto the diameter of mandrel 42. Slide 146 is adjusted to vary said wirecast for different size mandrels.

A bearing 151 is xedly mounted on H-beam 32 with rod 152 slidablyextending therethrough and a disc 153 is iixedly mounted on said rodwith coil spring 154 surrounding said rod between said disc and atubular slide 155 slidably mounted on said rod adjacent said tail center40. Rod 152 extends lengthwise of H-beam 32 and has a second tubularslide 156 slidably mounted thereon with a second coil spring 157surrounding said rod between said second slide and a bearing 158 iixedlymounted on said H-beam with rod 152 slidably extending therethrough. Acam 159 is iixedly mounted on the end of rod 152 and has a suitablyshaped cam surface 160 on the top thereof. A control lever 161 ispivotally connected to cam 159 and to a limit switch 162 for controllingsaid switch which is of a double throw snap-lock type for selecting adifferent set of said clutches.

A control lever 163 has a roller 164 riding on cam surface 160 for beingmoved thereby and which lever 163 is connected to a time delay switch165 for operating the same. A bearing 166 lixedly mounted on said H-beamhas rod 152 extending therethrough and a bolt 167 in threaded engagementwith said bearing and abutting said rod for at times locking said rodagainst movement.

A spring plate 168 is positioned in the path of carriage 35 and isconnected at one end by screw 169 to the top of H-beam 32 adjacent head41 and extends longitudinally of said H-beam. Compression springs 168aare mounted on H-beam 32 below plate 168 and a stop 170 is fixedlymounted on said H-beam beneath said spring plate while an invertedU-shaped stop 171 iixedly mounted on said H-beam extends above saidspring plate. A coil spring 172 connects the free end of said springplate to an upright arm 173 iixedly mounted on said H-beam tending todraw said spring plate upwardly. When carriage 35 rides onto said springplate it is thus resiliently retained from leaving the same.

As shown in FIG. 9, the Zero-Max drive 14 includes an input shaft 174connected to motor 15 for being rotated thereby and an eccentric 175 isxedly connected to said input shaft and is rotatably mounted inconnecting rod 176. A pin 177 pivotally connects one end of a pair ofspeed control links 178 and a main link 182 to connecting rod 176. A pin179 pivotally connects said speed control links to a lever 180 which isxedly connected to the axle 181 of control lever 16 pivotally supportedon the Zero-Max drive 14. Main link 182 has an angular portion 183pivotally connected by pin 184 to wedge ring 185 and said wedge ring hasa roller carrier 186 rotatably mounted therein with rollers 187 in wedgeshaped openings 188 and spring 17 tend to push said rollers to the smallend of said wedge openings 188. Output shaft 189 is xedly connected tosaid wedge ring and to pulley 13.

Foot pedal 190 is pivotally mounted on xed base 191 and is connected tocable 112 which runs over pulleys 192 and 193 to bar 106.

A manual control bar 194 is connected to cable 195 in housing 30 whichcable 195 runs over pulley 196 to solenoid 197 at one end and has aprojection 198 at its other end for engaging and operating a snap-lockswitch 199. Said bar 194 slides into housing 31. When bar 194 ismanually pushed to the left of FIG. 1, it closes the contacts of switch199 starting the head 41 to rotate and the carriage 35 to move, whilemovement of said bar to the right at any time will stop the machine.

Rails 11 have electrical switches 200, 201 and 202 mounted therealongfor being engaged and operated by slide plate 27. Switch 200 is astarting switch for motor 15, switch 201 is a stopping switch for motor15, and switch 202 is a safety switch for stopping motor 15 and head 41.

The operation of the present machine will now be described as used inthe production of wire reinforced hose, but it is to be -appreciated themachine can equally as well be used for other types of wrapping andwinding operations.

A mandrel 40 before being mounted on the machine is inserted into a tubeof a resilient material A, such as rubber, and thereafter mounted on themachine by inserting tail center cone in one end of said mandrel andhead cone 88 in the other end thereof. Said tail center is moved to theleft of FIG. 1 until the mandrel is rmly engaged and disc is in one ofthe teeth 107 of bar 106 so that it is impossible for said mandrel to beremoved from said cones accidentally.

Reel 3 containing a roll of wire 4, has its axle placed on rollers 2 forbeing rotataby supported and wire 4 is fed over pulley 13, aroundmultiple groove pulleys 29 and 28 and from pulley 29 to pulleys 33 and34 onto the right of roller 148, left of roller 149, and under roller ofthe caster making about a 90 bend and from there to and under projection96 of head 41. For the latter purpose lever 94 is raised by pressing anring 97, compressing spring 98 till the end of the wire 4 is on key 92,whereupon said lever is freed with springs 98 pressing projection 96 onwire 4 against said key holding the wire When fastening said wire end,carriage 35 is on spring plate 168 depressing the same against spring172 so that said carriage is restrained from movement.

Putting switch 206 in its closed position starts the Reeves Motor Drive43, 44 which runs continuously during the use of the machine. Withcarriage 35 on spring plate 168, said carriage has pushed slide 156against spring 157 and toward bearing 158 moving rod 152 to the right ofFIG. 4 throwing lever 161 to the right connecting electric clutch 46 tothe electrical circuit causing said normally open clutch to engagedriving shaft 47, and head 41 rotating said mandrel. The operatoroperates switch 204 to select either clutch 60 or 67 depending on thespeed he desires for carriage 35. Clutch 60 Will engage if selecteddriving chain 61 and miter box 62, sprocket 63 and thus chain 36 movingcarriage 35 along said rotating mandrel 42, whereupon wire 4 will becoiled along tube A as shown in FIGS. 1 and 4. As said carriage movesalong said tube liquid container 37 is pivoted placing brush 121 on saidtube placing la liquid, such as a solvent,

on the outside of the tube which solvent removes dust and other foreignmatter while producing a tacky surface on said tube.

When carriage 35 reaches slide 155 it starts to push said slide againstspring 154 which compresses and then pushes disc 153 against bearing 151moving rod 152 to the left of FIG. 4, moving lever 161 to the leftwhereupon switch 162 releases clutch 46 and engages clutch 54 whichrotates chains 51 giving a slower rotation to head 41. Also switch 162then open clutch 60 and engages either clutch 77 or 81 giving a reversedrive to miter box 62 through chains 78 or 79. Rod 152 at the same timeby cam 160 moves control level 163 tripping the time delay switch 165which energizes solenoid 197 and relay R-6. Solenoid 197 then pulls bar194 to the righ of FIG. 1 tripping switch 199 stopping the machine andrelay R-6 closes brake 49 stopping the mandrel rotation. When said timedelay switch 165 times out in about two seconds, for example, thecircuit is open.

The operator then cuts the wire 4 between the caster roller 150 and tubeA and feeds tape 39, for example, a nylon tape, from roller 126 aroundtape guide 39a to and around tube A, and wire 4 thereon adjacent tailcenter 40. The operator then moves bar 194 to the left of FIG. 1 closingthe circuit whereupon said mandrel again starts rotating drawing tape 39therearound as shown in FIG. 1 at the proper angle to provide a uniformspiral lap of the edges of said tape while carriage 35 is drawn by chain36 to the left of FIG. 1 until again said carriage trips tubular slide155 moving rod 152 and levers 161 and 163 to the right of FIG. 4 and isretained by spring plate 168.

Ring 97 is then pressed downwardly by the operator to release wire 4 andalso pedal 190 is depressed pulling bar 106 from disc 105 s0 that cone100 can be slid from the mandrel and thus tube A with coiled wire andtape can be removed from the mandrel as a wire reinforced hose.

It is to be appreciated the sprockets in housing 31 are sized to givevarious desired speeds to head 41 and chain 36 to obtain uniform pitchesto the wire and tape, but dierent pitches by using one of the clutches60 or 67 for winding the wire and one of the clutches 77 or 81 forwrapping the tape. Shafts 75 and 68 with their elements can beeliminated or additional similar shafts and elements employed to reduceor increase the speed variations available.

At the start, the operator closes either switch 204 for either clutch 60or 67 and switch 205 for either clutch 77 or 81 and thereafter switch162 is automatically operated to energize the proper clutch selected aswell as clutch 46 or 54.

In FIG. 16 elements R1 through R6 are relays while CT1 and CT2 areclutch controls.

The speed of head 41 can be varied also at any time by operating laconventional Electrical yRemote Control Unit 44a on the IReeves MotorDrive 44, at the desired speed.

As wire v4 is drawn from reel 3, slide plate 27 slides on rails and 11maintaining the wire at the proper tension. Should plate 27 trip switch201 Ithe motor 1'5 will be stopped and if plate 27 trips safety switch202 it will stop motor 15 and head 41.

The movement of plate 27 also is translated 4to control lever 16 bychains 24 and 18 controlling the Zero- Max drive 14. Referring to FIG.-9 the turning input shaft 174 turns eccentric 1-75 causing theconnecting rod 176 and the control links 178 and main link 182 lto moveup and down or back and forth depending upon the position of saidcontrol link as determined by lever 16 and link 180.

At the zero setting, the connecting rod 1.76 moves control links 178 andmain link 182 up and down through an arc at pin 177 leaving pin 184stationary. As pin 179 is moved along a vertical arc to the position inFIG. 9 by lever 16, output shaft 189 starts to rotate because connectingrod 176 is now giving back and forth 8 motion to main link 182 and wedgebody 185 at pin 184 as indicated by the arrows. This back and forthmotion of wedge body 185 turns output shaft 189 because rollers arewedged in wedge slots 188 in one direction of said Wedge 'body movementand freed in the opposite direction providing a free wheeling effect.Thus, Voutput shaft 189 is rotated in varying amounts determined by theposition of lever 16 and control link 178 at pin 179. 'Ihus shaft 189 isgiven a speed from zero to variable output speeds to ensure the properdraw olf speed of wire 4 on pulley 13.

Solenoid `5a is energized by micro-switch 5b being opened and closed bythe movement of speed control lever or arm 1'6 and when arm 16 is raisedto its horizontal position switch 5b is closed causing brakes 9 to beapplied. As soon as arm 16 starts to move away from this horizontalposition, switch 5b is opened releasing brakes 9 and starts the outputrotation of the ZeroJMax drive 14 to pick up. The operation of solenoid5a sends air to the top of cylinder 5 applying brakes 9 to reel 3stopping the same.
